- 256 KB of SRAM
- CPU cache consisting of separate 8 KB I/D and 8 KB system cache
- QSPI controller optimized for XIP from external serial NOR flash memories with support for quad and octal data interfaces
- SDRAM and external memory bus interfaces
- eMMC/SDIO interface through eSDHC peripheral
Ultra Low Power
- Flexible low-power modes with power and clock gating for optimal peripheral activity and recovery times. Stop currents of <340 nA, run currents of 200 µA/MHz, 5.8 µs wake-up from Stop mode
- Full memory and analog operation down to 1.71 volts for extended battery life
- Low-leakage wake-up unit with up to seven internal modules and 24 pins as wake-up sources in low-leakage stop (LLS)/very low-leakage stop (VLLS) modes
- Low-power peripherals and DMA for continuous system operation in reduced power state
Performance
- Arm® Cortex®-M4 core + DSP up to 150 MHz, single-cycle MAC, single instruction multiple data (SIMD) extensions, single precision floating point unit
- Up to 32-channel DMA for peripheral and memory servicing with reduced CPU loading and faster system throughput
- CPU cache consisting of separate 8 KB I/D and 8 KB system cache
- Cross-bar switch enables concurrent multi-leader bus accesses, increasing bus bandwidth
Cost Saving Integration
- 48 MHz internal reference clock capable of supporting full-speed USB device without an external crystal
- Integrated USB regulator to allow direct connection to 5V from USB cables
- Separate I/O power domain for several pins allowing interfaces without external level translators
- Analog voltage reference provides an accurate reference to analog blocks, ADC and DAC and replaces external voltage references to reduce system cost
HMI (Human Machine Interface)
- 32-Pin FlexIO block capable of interfacing to camera or displays
- External memory bus for connection to smart display modules
- Touch Sense interface supported by Kinetis® SDK software library
- GPIO pins with support for digital filtering
Mixed Signal Capability
- 16-bit analog-to-digital converter (ADC) with configurable resolution. Single or differential output mode operation for improved noise rejection
- 12-bit digital-to-analog converters (DACs) for analog waveform generation for audio applications
- Two high-speed comparators providing fast and accurate motor over-current protection by driving PWMs to a safe state
- Analog voltage reference provides an accurate reference to analog blocks, ADC and DAC, and replaces external voltage references to reduce system cost
Connectivity and Communications
- USB 2.0 on-the-go (full-speed) with USB transceiver. Intelligent design with embedded 48 MHz oscillator allowing for USB crystal-less system design. Device charge detect optimizes charging current/time for portable USB devices enabling longer battery life. Low-voltage regulator supplies up to 120 mA off-chip at 3.3 volts to power external components from 5 volts input
- Up to four UARTs with IrDA support
- EMVSIM module with ISO7816 smart card support
- Inter-IC Sound (I2S) serial interface for audio system interfacing
- Three DSPI and four I2C
